Hi.

Have a problem that i need som help with:
1. Have multipple raids working in a encrypted filesystem in CentOS 5.4 (i386): script file, crypt.sh

modprobe cryptoloop
losetup -e aes /dev/loop0 /dev/md0
(inserting password here)
then run
mount -t ext3 /dev/loop0 /mnt/raid5
Have been using this in CentOS for a long time and works like a charm.

2. Raids is now moved to another server with ubuntu server 9.10 (64bit)
Raid is detected fine and working.

Do the same thing again and get:
sudo modprobe cryptoloop (ok)
sudo losetup -e aes /dev/loop0 /dev/md0 (ok)
sudo mount -t ext3 /dev/loop0 /mnt/raid5 (failes with the following msg)
mount: wrong fs type, bad option, bad superblock on /dev/loop0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

ubuntu: cat /proc/crypto |grep aes
name         : ecb(aes)
driver       : ecb(aes-asm)
name         : cbc(aes)
driver       : cbc(aes-asm)
name         : cbc(aes)
driver       : cbc(aes-asm)
name         : aes
driver       : aes-asm
module       : aes_x86_64
name         : aes
driver       : aes-generic
module       : aes_generic

Is there compatible issues here?
Can it be that the old server was using i386 arch and the new is 64bit?
losetup version differs?

Any insight is appreciated.
